the greatest charm perhaps the plant possesses ; for though the 
flowers are large, they are not showy, not more so than Port- 
landia, or other white corollas whose tubes have a tinge of green. 
Mikan referred the genus to Convolvulacea, Meisner to Bignont- 
acee, Lindley and Miers (with more propriety) to Solanacee, and 
the latter to a separate group, which he calls “ Metternichiee,”’ 
along with Sessea and Cestrum. There is probably but one 
species. Dunal takes up, indeed, W/. affinis of Presl, but as 
something more than doubtful; and he has a “Metternichia ? 
megalandra,’—querying the genus,—a Colombian plant of Mo- 
ritz (n. 827). J. Principis flowers with us, in the stove, in 
August. 
Descr. Our flowering specimens constitute a shrub three to 
four feet high; in its native climate it attains a height of 
twenty-five feet: much branched, dranches terete, and, as is 
every part of the plant, glabrous. Peduncles terminal and in the 
axils of the terminal leaves, short; or the inflorescence may be 
called a leafy, somewhat panicled raceme. Calyx campanulate, 
irregularly five-cleft, segments erect. Corolla white, broad- 
infundibuliform ; the ¢wbe greenish, angled; Jimd spreading, 
large, plicate, as in Solanum or Convolvulus, cream-white, the 
five broad lobes bifid, and waved or plaited. Stamens five, ex- 
serted; filaments filiform, unequal. Anthers oblong. Ovary 
oval. Style longer than the stamens. Stigma two-lobed. _ Cap- 
sue an inch and a half or sometimes two inches long, cylindrical, 
tapering, five-valved, the base enclosed in the persistent calyx.
